“…For this particular scenario, since the simulation time is relatively short (around 180 s), stable wind and temperature may be a reasonable approximation. Arguably for such a scenario, satisfactory simulation results may be obtained by using simpler models, such as SLAB (Ermak 1990), HEGADAS (Colenbrander 1980), DEGADIS (Spicer et al 1989), HGSYSTEM (Witlox & McFarlane 1994), PHAST (DNV 2007), ALOHA (EPA 2006), SCIPUFF (Sykes et al 2007) and TRACE (Systems 2009). Nevertheless, the aim of this study is not to find the best simulation tool for the particular vapour dispersion scenario; instead it is to find an enabling method (i.e.…”
